The Ampère’s Law Song

Refrain:

C Em F C F G

Mr. Ampère’s magical, mystical, wonderful law!G C G7 F C G7 C

Of Maxwell’s equations, it is the longest and strangest of all!

C F G C

On the left side, he wrote circulation

C F G C

Of magnetic field, ‘cause it was neat.

C F G C

On the right hand side of his equation --C F G C

Mu-naught I – he thought it was complete.

(Refrain)

F C G C C7

Decades later, Maxwell saw disaster,

F C G C

Although he thought of Ampère as a saint --F C G C C7

In between the plates of a capacitor

F C G C

The right side’s zero, but the left side ain’t! 

C F G C

To fix this problem, he added to the right side

C F G C

Displacement current, a brand new quantity!

C F G C

It started mu-naught eps’lon-naught and ended by

C F G C

The time derivative of phi-sub-E.

(Refrain)

C F G C

And so to Maxwell the myst’ry was reveal-ed--

C F G C

He saw how light could move through empty space.

C F G C

The changing B-field made the changing E-field,

C F G C

And vice-a-versa, all at the perfect pace.
